cokn-ov 111 citizen of the United States, and resident of New Rochelle,in the county ofWes chester and State of New York, have invented certainnew and v useful llmprove ments in Coke-Uven-Wall Constructions,- ofwhichthe following is a specification.

My present invention relates to coke ovens of the well known and widelyused type in which each oven battery comprises a plurality ofhorizontally elongated coke oven chambers, each adjacent pair of whichare separated by a heating wall formed with flue passages through whichthe heating gases flow. Tn this type of even as hereto-.

fore constructed .it has been found practically impossible to preventleakage between the oven chambers, and the flue spaces in the endportions of the adjacent heating walls The brick work forming the endsof the heating wall is subjected to temperatures which average lower,and fluctuate more than the temperatures to which the bodies of theheating walls are subjected, and the resultant relative expansion andcontraction of the bricks in the end portions: "of the heating wallstends to open the brick work joints. The mechanical stresses to whichthe brick work at the ends of the heating wall is subjected indischarging the ovens and in removing and replacing the oven doors alsotends to loosen and open the joints. The gas leakage thuscaused isobjectionable as it involves a wastage of gas and by-products andinterferes with the desired uniformity in oven heating.

The general object of the present invention is to provide a specialconstruction at the ends of the heating walls which will eliminate orsubstantially minimize leakage between the oven chambers and the fluespaces in the oven wall. lln carrying out my invention ll employmetallic flashplates fill or armor and so shape this metallic armor andthe adjacent brick work that the armor clamps the bricks forming the endand adjacent side portions of each heating wall together, and therebyprevents the corresponding joints from opening under the normaloperating conditions to which they are subjected. The armor employed mayalso serve the purpose for which armor has heretofore been placed on theends of the oven heating walls; namely of protecting specification ofLetters Patent.

the brickwork from water and mechanical in uriesand to form doorwayframes for the oven doors.

The various features of novelty which characterize my invention arepointed out with particularity in the claims annexed to and forming apart ofthis specification. For a better understanding of the invention,however, and the advantages possessed by it, reference should be had tothe accompanyin drawings and descriptive matter in which haveillustrated and described preferred embodiments of my invention,

@f the drawings:

Figural is an elevation of a portion of a coke oven battery;

Fig. 2 is a section taken on the line 9 of Fig. 1 but on a smallerscale;

Fig. 3 is a partial sectional plan on the line 33 of lEig. 1; and

Figs. 4:, 5, 6 and 7 are sectional plans illustrating modified forms ofconstruction.

Tn the drawings and referring first to Figs. 1, 2 and 3, T have shown aportion of a coke oven structure which, in its general form, is of thetype now in most common use in large capacity by-products coke ovens.This coke oven structure is provided with horizontally elongated cokingchambers A separated by heating walls in which are formed verticalheating flues B. The sides of the heating walls are formed by thesocalled liner bricks C and C and the adjacent fines are separatedbywalls formed b%socalled bottle bricks The end flue in each heating wallhas its outer wall formed by bricks E. The bricks C and D may be of theusual form, but the bricks C have their outer edges bevcledat C forengagement by the correspondingly beveled shoulders E of the bricks 1E,and the latter are formed with tongue portione E which extend betweenand are engaged by the flat 1nner sides of the adjacent bricks C". Theshoulders C of the bricks C at the two sides of each heating wall endare oppositely beveled so that the shoulders E of the bricks E hold thebricks C engaged by them against the tongue portion E With thisarrangement a relatively long joint I is' too I ing action of theshoulder E of the bricks E exerted against the beveled surfaces C of thebricks C. To make this clamping action permanently effective, and to-mini mize the tendency of the brick shoulders E faces of the bricks Eand the sides of the shoulders E of the bricks E forming each endheating wall are incased in a trough Yshaped metallic fiashplate orreinforcing member F ordinarily made of castv iron.

against movement away from the oven structure by the usual ovenbuckstays G. The flashplates form the sides of the doorways at the endsofthe oven chambers,'and are shaped to correspond to the type of dooremployed. A

' In the particular door and doorway construction illustrated in Figsl,2 and 3, the doors H employed are shaped to move freely between theedges of the flashplates, and the metallic frame H of each door and theadjacent flashplate edges are so relatively doorway, and the doors aresecured in place by locking bars L engaging brackets Q carshaped as toprovide a narrow trough shaped groove J in which the usual joint lutingmaterial may be placed. Preferably the doorways are provided withmetallic sills at their bottoms, and metallic lintels K connect theflashplates at the tops of the iiedJoy the buckstays G.- The specialdoor construction illustrated and the shaping. of the flashplates toconform to this door construction, although novel with me, is notclaimed herein, but. is claimed" in my copending application, Serial No;437,6 l7.

In the modification shown in Fig. 4 each I of the bricks E of theconstruction shown inF'igs. -1, 2 and 3, "is replaced by two bricksEAand EB each of which is formed- -with one shoulder E, and a portion ofthe tongue E In Fig. 4 I have illustrated a GA externallv modifiedform'of door HA, and 'a flashplate shaped to provide a shoulder Gragainstwhich a ortion of the metallic frameof the door' A abuts, at theinner or bottom edge of. the trough provided to 7 rece ve the lutingmaterial. f Y

- In the. modification shown in Fig. 5, the

' bricks E'Oforming the outer walls of the end fiues B are rectangularblocks which fit between the liner bricks G, and the latter are-recessedat theirouter corners as indicated at C to receive the sides of thetrough shaped flashplates GB which, in this construction,- not only abutdirectly against the recessed sides of the bricks C but also against theouter edges of those bricks.

The construction illustrated in Fig. 6. differs from that shown'in Fig.5 in that the blocks project out beyond the outer above.

I wall bricks between them.

edges of the bricks C and small rectangular bricks ED- are interposedbetween the ends of the bricks C and the flashplates GG,

-which are shaped to fit against the outer .struction, howeveiythe outerfaces or edges Ihe flashplates F are engaged and held,

of the bricks C and the shoulders E are beveled, not as shown in Fig. 3but 1n the opposite direction, and the bricks C are rectly sealed by theflashplates GD. The I differentiated-from the forms shown in Figs.

3, 4, 5 and 6 are claimed in my co-pending application, SerialN0.437,64:7, referredto In the normal contemplatedmode of constructing acoke oven comprlsing the improvements disclosed herein, the flashplatesare set in place before the heating walls are built, and the bricks atthe ends of the heating' walls are laid against the flashplates thusinsuring the proper initial relative arrangement of bricks andflashplates. When thereafter theovens are heated up and the partscontract and expand with the varying,

temperatures to Which'they are subjected in operation, the buckstays atthe opposite ends of each heating wall which are connected by .the'usual tie rods (not shown) hold the flashplates at all times snuglyagainst the ends of the'heating wall. In consequence of this and thespecial shaping and arrangement of the flashplates and adjacent brickwork, the flashplates at all times positivel hold the liner bricks atthe sides of cum endflue B against the portion of the end leakagebetween the end flues and the oven chambers since the leakage paths arecomparatively long, and with the bricks at the opposite sides oftheq'oints held firmly together the joints, in .case leakage develops,are quickly rescaled by dust or residue carendwall-bricks. Thispractically eliminates raeaeea ried into the joints by the gases leakingtherethrough.

While in accordance with the provisions of the statutes 1 haveillustrated and described the best form of my invention now known to me,it will be apparent to those skilled in the art that changes may be madein the form of the apparatus disclosed without departing from the spiritof my invention as set forth in the appended claims, and that certainfeatures of my invention may sometimes be used to advantage without acorresponding use of other features.

Having now described my invention what claim as new and desire to secureby Letters Patent, is: v

1. In a coke oven structure comprising coking chambers and interposedhollow heating walls, the improvement which consists of brickworkforming the outer end.

and the side walls of the flue spaces ,in the ends of the heating wallsand metallic armor for the ends of the heatingwalls', said armor andbrickwork being so relatively arranged and disposed that the armorpositively holds the side wall bricks against spreading.

2. In a coke oven structure comprising coking chambers and interposedheating walls formed with vertical heating flues, the combination withbricks forming the side walls of each heating wall end flue,: of bricksinterposed between the side wall bricks of each end flue to form theouter end wall oi? the flue, and metallic armor for the ends of theheating walls arranged to positively hold the sidewall bricks againstthe interposed bricks.

3. In a coke oven structure comprising coking chambers and interposedflue heating walls, the improved heating wall end construction"comprising spaced apart liner bricks having their outer ends oppositelybeveled and end wall bricks comprising tongue portions interposedbetween the liner bricks and laterally projecting shoulders undercutxtofit against the beveled ends of the liner bricks and a trough shapedmetallic member incasing the outer faces and the side edges of theshoulders of the end wall bricks.
